[2442.62 --> 2447.34] so i think there are like some obvious questions that people will probably have one of them is is um |
[2447.98 --> 2451.90] what does google use dart on right now that that you can kind of share with us |
[2454.14 --> 2461.10] sure uh we have an internal sales tool that uh this this is a great story um it's sort of sort of like |
[2461.10 --> 2465.66] the widow maker project in a sense that they've tried to re rebuild this system a bunch of times and you |
[2465.66 --> 2470.70] know legacy software right there's a bunch of decisions made and um and they try to rebuild rebuild it and then |
[2470.70 --> 2479.82] uh recently uh they they did a full rewrite in dart and angular dart and delivered the project on time |
[2479.82 --> 2486.38] and blew away everyone's expectations and now that's a successful deployment we also have other apps like |
[2486.38 --> 2491.98] google elections has a really neat app to help track elections around the world and numerous other |
[2491.98 --> 2498.22] internal tools that we're not quite ready to to share yet but there's a page on our site called who uses dart |
[2498.22 --> 2504.86] that references some internal and a bunch external as well awesome so there are so there are some |
[2504.86 --> 2509.42] external uh can you kind of kind of allude to some of those that that without having to go to the site |
[2509.42 --> 2514.70] here oh sure so uh one of my favorite is this company called soundtrap and what i really like |
[2514.70 --> 2519.58] about them is not only do they use dart but they also use some of the really cool new html5 features |
[2519.58 --> 2526.94] like web rtc which is real-time collaborative communication and some of the media stuff like get user media |
[2526.94 --> 2534.22] and audio and video so they built a collaborative music authoring uh app with dart and web rtc so it's |
[2534.22 --> 2541.66] such a cool thing another great story is a startup called blossom and i like i like their story because |
[2541.66 --> 2549.66] they were originally on javascript and uh let's see backbone and they over time gradually their users |
[2549.66 --> 2554.46] didn't even know it started swapping out some of their components for dart components and so that that |
[2554.46 --> 2558.38] was really cool to show that yes you can take an existing javascript app and if you like what dart |
[2558.38 --> 2565.66] has to offer you don't need to rewrite the whole thing you can do it piecemeal awesome so yeah i mean |
[2566.86 --> 2571.10] yeah i don't have much to say to that other than the fact that this is obviously something that is |
[2571.10 --> 2576.94] going to continue going in that direction and i think that that's a that's a good thing so just to |
[2576.94 --> 2583.18] even though we are from google and our only objective with this project here is to make people more |
[2583.18 --> 2590.30] efficient at doing web applications so everything is open and we are very receptive to to feedback so |
[2590.30 --> 2596.38] we can make it better so if people are trying it out and they have problems in an area we would like |
[2596.38 --> 2602.06] to hear the feedback so we can make the system solve that problem one thing i notice here is that |
[2602.86 --> 2609.10] similar to go uh you don't actually see any google brands on the dart website that's obviously a uh |
[2609.10 --> 2616.30] uh on purpose correct that's right it's an open source project it's for the web the spec itself |
[2616.30 --> 2622.94] is in the ecma process now um it's it's no secret that googlers work on the project but like a lot of |
[2622.94 --> 2630.78] other successful projects for the web it really is for and of the community so the the million dollar |
[2630.78 --> 2636.30] question and and we kind of talked about this a little bit before um but but how do you know that you've |
[2636.30 --> 2641.74] for lack of a better term how do you know that you've won with dart like when do you feel like |
[2641.74 --> 2648.86] okay you've gotten to a point where dart is is here to stay when every developer is building for the |
[2648.86 --> 2655.02] modern web on mobile devices and uh i don't think we can get there without something toolable and |
[2655.02 --> 2665.18] productive like dart yeah so um yeah that's a good answer but this the um so it bottoms out to that |
[2665.18 --> 2672.30] uh we will continue to innovate to make sure the web uh the web platform gets better and better over |
[2672.30 --> 2677.58] time uh getting success with the programming language is is hard because people have to like |
[2677.58 --> 2683.34] it they have to like the feel of it when they type in the code at this point it looks really good the |
[2683.34 --> 2689.34] projects we've seen working working with dart they like it and it's growing right now the community both |
[2689.34 --> 2696.30] inside our company and also outside so we have been around we've been working on this for three years |
[2696.30 --> 2704.54] success uh is coming i think it looks pretty good if we have the same uh growth over the next two years |
[2705.10 --> 2712.14] i would be really really happy because just having the competition going means that even other web |
[2712.14 --> 2717.18] programming language they will might learn something from what we did in dart and that will lift the whole |
[2717.18 --> 2723.34] industry hopefully so it's certainly an idea that we can we can make everything better not only the |
[2723.34 --> 2729.58] dart system yeah you get the feeling that that one of the goals of dart is not just to like catch up |
[2729.58 --> 2734.14] and be where web programming is now but but one of the goals of dart is to move web development forward |
[2734.14 --> 2738.54] and i think that's that's a pretty good and you know ambitious but but also one that's necessary |
[2738.54 --> 2744.06] here i don't know if we should go back and talk about v8 but that's sort of the same with the v8 project |
[2744.06 --> 2750.14] uh when we started out uh there was not a lot of javascript code being executed because it was very |
[2750.14 --> 2757.42] slow and and you basically have to have look into the future and figure out what do people want in the |
[2757.42 --> 2764.62] future when it comes to executing javascript and we decided that the more speed you have the more |
[2764.62 --> 2771.18] innovation the application developers would go for and that's also what happened and in the process |
[2771.18 --> 2779.42] all the other browsers got fast javascript engines as well and i think that's great yeah |
[2780.30 --> 2785.98] that's that's one of the things about um i don't know about javascript about the current state of |
[2785.98 --> 2790.06] browsers right now is you'll see these ships of browsers and it'll be like you know some javascript |
[2790.06 --> 2796.06] uh efficiency some some performance increase but but that kind of almost feels like it's plateauing to |
[2796.06 --> 2800.94] a to a degree where like the the major like you said the the the benefits you got when like v8 started |
[2800.94 --> 2805.50] coming and things like that were like were much bigger gains than the ones you're seeing right now |
[2805.50 --> 2811.42] um does dart follow that same trend or or you know obviously dart is young so there's a lot of |
[2811.42 --> 2816.46] performance increase to come in the future but but you're not plateauing now or there are from ship |
[2816.46 --> 2822.54] to ship are they are they major efficiency increases that you're seeing that is getting faster and faster with |
[2822.54 --> 2830.38] each release uh we're doing and we are focusing on it and uh because start is more structured than |
[2830.38 --> 2836.94] uh then as we mentioned with javascript uh you would see that over time that uh dart will get the same |
[2836.94 --> 2847.42] kind of performance as uh as java basically except for if you're doing a hardcore um double computation |
[2847.42 --> 2853.66] uh yeah but that's not our goal but for ordinary uh object-oriented programs we should approach that |
[2853.66 --> 2860.46] kind of speed so we're aiming high uh but you'll see performance improvements over at least the next few |
[2860.46 --> 2869.50] years uh yeah no no plateauing in sight yeah you heard it here first we're going to have a web development |
[2869.50 --> 2877.10] that is as fast as system programming that's a good thing so speaking about performance the the last |
[2877.10 --> 2881.98] release we had 1.3 really focused on server-side performance one of the questions we get all the |
[2881.98 --> 2887.18] time is is there a node for dart i think developers like what they see but they know they have to write |
[2887.18 --> 2891.34] some server code and client code and so they want to know can they do dart on the server and so the |
[2891.34 --> 2897.98] answer is a resounding definitely uh we the virtual machine runs on the command line uh just like you |
[2897.98 --> 2904.38] know ruby or python or or v8 and you can get access to files and directories sockets there's a built-in |
[2904.38 --> 2909.82] web server built-in web sockets ssl and we've recently turned our performance attention over |
[2909.82 --> 2915.74] to the server side story as well so the story is looking really good awesome oh yeah we since it's |
[2915.74 --> 2921.18] a language project we also have to say that our internal tools are mostly written in dart so the |
[2921.18 --> 2929.50] dart to js compiler is of course written in dart and also the analyzer nice so for people that are just |
[2929.50 --> 2934.46] getting started what's the what's the recommended way to to to do just that to get started with dart |
[2935.34 --> 2943.74] on the website uh there is a one hour code lab uh called try dart and uh you build up your pirate name |
[2944.62 --> 2948.78] but it's really great it walks you through the features of the the language it walks you through |
[2948.78 --> 2952.86] some web programming and yeah just about an hour you're gonna have a working dart app |
[2952.86 --> 2962.78] so the website is dartlang.org okay awesome i think obviously i mean it's an entire ecosystem |
[2962.78 --> 2967.50] it's not just a language we can sit here and talk about it for for a long time and and i would love to |
[2967.50 --> 2972.22] uh to do just that but we try and keep the show down to about an hour so i i have a feeling that this |
[2972.22 --> 2976.54] is going to be one that we're going to want to to have another show on in the future to see where it goes |
[2976.54 --> 2981.34] um but but for now i want to give you guys an opportunity anything else that you want to kind of |
[2981.34 --> 2984.46] to mention about dart for for the people to hear before we move on |
[2987.98 --> 2994.70] well the uh we hope that people try it out and give us their opinion and and hopefully it's a good |
[2994.70 --> 3003.10] one um that's pretty much it we'll continue to work hard on making it better over time um so that's |
[3003.10 --> 3009.18] pretty much it i think it's it's very hard to convince people to use another language over the radio |
[3009.18 --> 3014.22] uh people have to try it out and have to feel the program is to figure out if something they can be |
[3014.22 --> 3020.94] productive in so it's a very personal uh kind of decision what's the recommended way to to give |
[3020.94 --> 3029.02] feedback is it through the uh the mailing list or you can file a file an issue uh on the issue tracker or |
[3029.02 --> 3036.46] you can send an email to to the mailing list that'll be answered i'd love to ask all developers who are |
[3036.46 --> 3043.26] interested in dart to go check out pub.dartlang.org that's our hosting site for packages and you'll |
[3043.26 --> 3048.38] find a tons of great stuff in there from the community um and when when you're building for the |
